The problem
Following tenders and permits is manual work in which a relevant publication is easily missed.
Approach
Tenderwacht reads public tenders from TenderNed and TED, Vergunningwacht reads permit notices. A user saves a search and receives an email on a match.
Both run on the same architecture as KVKBase: Astro, a Worker with scheduled jobs and one database.
Result
Tenderwacht has been live since October 2026, with a free and a paid tier. Vergunningwacht is online and still being built.
